Transmit diversity vs. spatial multiplexing in modern MIMO systems

A contemporary perspective on the tradeoff between transmit antenna diversity and/nspatial multiplexing is provided. It is argued that, in the context of most modern wireless/nsystems and for the operating points of interest, transmission techniques that utilize/nall available spatial degrees of fre...
